Hardware traffic generator using linear feedback shift registers for testing of memory subsystems

A method comprising:

• generating a linear-feedback shift register output (an LFSR output) for controlling a probability of sending a read command or a write command;
• comparing the LFSR output to a range of prospective LFSR-outputs;
• sending a command to read from a memory or a command to write to a memory if the LFSR-output is within the range;
• and
• sending no command to read from the memory and no command to write to the memory if the LFSR-output is outside of the range.

An injection determiner, comprising:

• a linear-feedback shift register (LFSR), for generating an LFSR-output to control a probability of sending a read command or a write command;
• wherein the injection determiner is for:
• comparing the LFSR-output to a range of prospective LFSR-outputs;
• sending a command to read from a memory or a command to write to a memory if the LFSR-output is within the range;
• and
• sending no command to read from the memory and no command to write to the memory if the LFSR-output is outside of the range.
